"Temporary Ponds: a natural habitat to be protected!"

Changes in agricultural and livestock practices

> Drainage

MTP's are often related to unproductive areas in the agricultural matrix. Therefore, in addition to clogging its area, farmers also drain the ponds when they are in the aquatic phase. To this end, a drain is open to allow water that is collected in this depression to flow away, diminishing the waterlogging content. This will allow these plots of land to be used for agricultural purposes but represent a threat to habitat destruction. The drainage of soil decreases or eliminates the amount of water accumulated, causing species disappearance. Simultaneously, it will allow a progressive increase of perennial helophytic plants which in turn will correspond to the decline of typical annual plants that are associated to MTP. In the SCI of Southwest Coast it was observed that the draining is usually followed by soil excavation and intensive planting, so the seed bank and the forms of resistance are progressively destroyed. If no earthmoving occurs these situations may eventually be reversed.

The following images illustrate some of the existing drainage ditches in the region.
